essayez ceci :
set nocount on;
declare @t table (id char(36), x char(1))
insert into @t (id, x)
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'A' union

FOR XML PATH('')

FROM @t p1
GROUP BY id
SORTIE :

MODIFIER
sur la base du commentaire d'OP concernant la nécessité de l'exécuter pour une requête existante, essayez ceci :
;WITH YourBugQuery AS
(
--replace this with your own query
select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' AS ColID , 'A' AS ColX
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'B'
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'C'
union select '61E77D90-D53D-4E2E-A09E-9D6F012EB59C' , 'D'
union select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'E'
union select '7ce953ca-a55b-4c55-a52c-9d6f012ea903' , 'F'
)
SELECT p1.ColID,
stuff(
(SELECT
' ' + ColX
FROM YourBugQuery p2
WHERE p2.ColID=p1.ColID
ORDER BY ColID, ColX
FOR XML PATH('')
)
,1,1, ''
) AS YourValues
FROM YourBugQuery p1
GROUP BY ColID
cela a le même ensemble de résultats que celui affiché ci-dessus.
